In her 1929 autobiography Cradle of the Deep, silent film star Joan Lowell revealed a dramatic childhood aboard her father’s trading vessel: She’d seen a man eaten by sharks, performed an amputation, and, when the ship caught fire and sank, swum three miles to the Australian coast with “drenched kittens” clinging to her shoulders:

I was conscious of only the pain caused by the salt water on my bleeding cuts and scratches. Each stroke I took was like a knife cut, and I couldn’t shake the drowning kittens off. Perhaps to those cats I owe my life, for the pain made me so mad I fought on and on, toward the lightship which seemed to go farther away instead of closer.

When it was published, sailing writer Lincoln Colcord identified 50 inaccuracies and called her to account. It turned out she’d made the whole thing up: Her father had worked on the boat for about a year, and she’d made one trip on it. Simon & Schuster reclassified the book as fiction and released a statement saying it had been “published in good faith, not as a literal autobiography but as a teeming yarn, fundamentally a true narrative but inevitably … embroidered with some romanticized threads.”
